Two bodies of masses m1 and m2 are dropped from heights h1 and h2 respectively. They reach the ground after time t1 and t2 respectively. Which of the following relation is correct?
1
\(\frac{{{t_1}}}{{{t_2}}}={\left( {\frac{{{h_1}}}{{{h_2}}}} \right)^{\left( {\frac{1}{2}} \right)}}\)
2
\(\frac{{{t_1}}}{{{t_2}}}=\left( {\frac{{{h_1}}}{{{h_2}}}} \right)\)
3
\({{{t_1}}}{{{t_2}\;}}={\left( {\frac{{{m_1}}}{{{m_2}}}} \right)^{\left( {\frac{1}{2}} \right)}}\)
4
\(\frac{{{t_1}}}{{{t_2}}}=\left( {\frac{{{m_1}}}{{{m_2}}}} \right)\)
